Civil engineering and tunneling company Verhale has won two further contracts from Thames Water to refurbish water mains at London’s Victoria and Euston stations.
This comes after the company was awarded the contract to replace the trunk line at Fortis Green in Haringey, north London.
The contract was signed by Thames Water as part of a major London-wide water asset upgrade program in Asset Management Period 7 (AMP7).
The recent awards bring the total value of work awarded under the scheme to Valhalle to £24.8m.
At Victoria Station, Barhale will upgrade more than 1km of cast iron water mains. The work he is divided into two sections. The first is a 609 meter stretch between Eaton Square and Victoria Street, and the second is a 412 meter stretch from Wilton Road to a point south of the intersection with Warwick Way.
At Eversholt Street, near Euston Station, Valhalle will upgrade a 660m long cast iron water main using 355mm SDR17 polyethylene pipe, combining open cut and sliplining.
Shane Gorman, Verhale’s southern regional water director, said the busy nature of both sites had a major impact on the engineering solutions.
“These are two of the most important rail gateways to the capital, with thousands of passengers passing through them every hour,” he said.
“The roads around each site are also very busy, so we have developed an approach that not only protects the future water supply of each area, but also minimizes the impact on local communities, businesses, rail and roads. It was important to the user.”
Barhale engineers will slipline existing water mains using launching and receiving pits. This means that the large-scale confusion that can be caused by continuous grooves can be avoided. It also reduces the environmental impact compared to traditional open-cut construction methods, Verhale said.
“We are very pleased that Thames Water has won these awards for their plans in such a sensitive location and has shown confidence in Verhale. I look forward to working closely with the Water team,” Gorman added.
Esther Sharples, Verhale Operations Director in London, said: “We are committed to keeping water running for Londoners and this multi-million pound investment will further future-proof our network.”
“Working with Barhale to invest in innovative technology to upgrade aging pipes in Victoria will also reduce disruption for customers in downtown central London.”
Handover and commissioning is expected to take place at Eversholt Street in spring 2024 and at Victoria Station towards the end of 2024.
In June last year Verhale was appointed by Thames Water to reroute part of a water main that crosses the route of High Speed 2 (HS2) in north London.
